Abstract

L'invention concerne un procédé pour obtenir des données d'état de session préalablement stockées pour une session entre un système comprenant une pluralité de nuds et un dispositif client qui comprend l'obtention d'un identifiant de session spécifiant la session et le hachage de l'identifiant de session. Une carte de hachage actuellement valide est recherchée. La carte de hachage mappe un hachage de l'identifiant de session aux nuds pour une configuration de système actuelle. La recherche est effectuée afin d'identifier un noeud de système sur lequel les données d'état de session pour la session sont stockées. Si les données d'état de session ne sont pas localisées à l'aide de la carte de hachage actuellement valide, au moins une carte de hachage de génération antérieure qui est valide pour une configuration précédente du système est recherchée. Lors de l'identification du noeud de système sur lequel les données d'état de session sont stockées, les données d'état de session provenant du noeud de système sont récupérées. Les données d'état de session sont utilisées pour établir la session.
